'expertly-crafted' originates from the combination of 'expertly' and 'crafted'. 'Expertly' comes from 'expert', which originates from Latin 'expertus', meaning 'tried, tested'. 'Crafted' comes from 'craft', which has Old English origins in 'cræft', meaning 'strength, skill'.

'Expertly' evolved from the Latin 'expertus' through Old French 'expert', and 'crafted' evolved from Old English 'cræft'.

Initially, 'expertly' meant 'tried or tested', and 'crafted' meant 'strength or skill'. Over time, they combined to mean 'skillfully made'.
